JOHN E OARROLL, OF PHILADELPHIA, PENNSYLVANIA.

ROOF-VALLEY.

SPECIFICATION forming part of Letters Patent No. 373,129, dated November15, 1887.

Application filed July 26, 1887.

To all whom it may concern:

Be it" known that I, JOHN E. CARROLL, a citizen of the United States,residing at the city and county of Philadelphia, and State ofPennsylvania. have invented certain new and useful Improvements inRoof-Valleys, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, of which-Figure 1 is a transverse section as applied to a valley between tworoofs, the protectingshingle being on one side removed. Fig. 2 is alongitudinal section, in perspective, of the two overlapping platesdetached from the roof.

This invention is an improvement in metal lic roof valley plates forcovering the V-shaped gutter formed between the contiguous inclinedsides of two adjacent roofs; and its object is to provide such a platewhereby the water within the same will be carried away and preventedfrom flowing or coming into contact with the wooden part of the roofunder circumstances hereinafter mentioned.

One feature of the invention consists in providing the said plates withlongitudinal ledges or bends, so as to leave a channel on the sides ofthe inclines of the plate, above the bottom or apex thereof, saidchannel being covered or adapted to be covered by the usual metallic orwooden shingles, thereby leaving a protected passage-way for theoverflow-water from rain or melted snow and ice, which may back up intothe channel when the central main channel or gutter is filled up withice, snow, or

other obstruction.

Another feature of the invention consists in providing the overlappedends of the successive plates with transverse corrugations, therebyleaving a comparatively great space between the overlapping ends of thelower and upper superposed plates,in order to avoid the capillaryattraction which, when the plates are smooth andeven, and thereforeclose-lying, sometimes causes the water to find its way up between theplates to the boards to which they are nailed, and thus rendering'thewood liable to decay.

Referring to the drawings, AA, Fig. 1, are two roofs whose contiguityforms a V-shaped valley, V, along which are secured the continuous linesof metallic plates B, conforming Serial No. 245,3ll. (N0 model.)

to the shape of that part of the roof, and secured to the roof'boards bymeans of the usual nails, it. These plates are usually plane, and thewooden (slate or metal) shingles c extend over the sides or edges, andwhen ice forms Within the gutter it frequently occurs that water forcesits way beneath the overlapping shingles to the wood beneath, therebyinjuring the latter and causing it to rot. In order to obviate thisdefect, I form the valley-plates as shownthat is to say, I provide alongthe sides of the plates two parallel longitudinal bends or ribs, D d, asshown, which form, when the shingles E are put on, continuous channels Fon each side of the apex of the valley. Now, if the latter fills up withice, the water will find its way beneath the shingles E into thechannels F, (which are protected from the snow and ice by the shingles)and thence run off to the roof or to the conducting-spout. The upperridge, d, forms a breastwork against the rush or passage of the water tothe upper edges of the platesthat is to say, when it would come intocontact with the boarding.

When metal shingles are employed, instead of allowing the lower endsthereof to project over the 'ribs D, I now prefer to turn the same downagainst the side of the lower ridge, D, as shown in the drawings. Theplates are made in sections and the adjacent ends of the severalsections fit one upon the other, as seen in Fig. 2.

I am aware of the fact that roof-valley plates having a single ledge oneach side somewhat similar to ledges D have been known.

In order to prevent water being absorbed by capillary action between thescams or j oints of these overlapping plates, and thus drawing the waterup to the wood-work beneath, I provide the upper end of each sectionwith transverse corrugations, G, and extend the upper or plane end overthe same, preferably bending down its front edge, as shown in Fig. 2.Thus air-spaces are left between the plates, which, so to say, serve tobreak up the capillary attraction.

Having thus described my invention,I claim as new and wish to secure byLetters Patent-- 1. As a new article of manufacture, a roofvalley plateprovided with two longitudinal continuous ribs or ridges, as D d,forming an intermediate channel, substantially as and for the purposeset forth.

2. The combination of the roof, the series of valley-plates providedwith the two longitudi- 5 nal continuous ridges and intermediatechannels, and the shingles covering said channels,

substantially as and for the purpose set forth.

3. A roof-valley consisting of a series of superposed plates, of whichthe ends of the an [O dcr plates are transversely corrugated and theoverlapping part of the upper plates a plane surface, substantially asand for the purpose set forth.

In testimony whereof I havehereunto affixed my signature this 25th dayof July, A. D. 1887. I5

JOHN E. CARROLL.
